| 20110214422 | RICH FUEL MIXTURE SUPER-TURBOCHARGED ENGINE SYSTEM - Disclosed is a super-turbocharger system that increases power and efficiency of an engine. The system uses the exothermic properties of a catalytic converter to extract additional energy from exhaust heat that is used to add power to the engine.
